Main Difference between Conventional Fire Alarm and Addressable Fire Alarm Systems
The conventional fire alarm system is that in case of fire indication, it will only detect the whole floor. It cannot pinpoint the exact location of the triggered alarm in the floor. The reason is that the sensors and devices triggers when the input cross certain threshold and send electrical signal to the main control panel through the common wire. Therefore, the main penal detects it as the whole zone (circuit).
Since it cannot pinpoint the exact location of the fire in the building, it is difficult for fire fighter to find the exact location and extinguish the fire before it cause further damage.
The addressable fire alarm system assigned each individual devices a unique address. It is a digital updated version of the conventional fire alarm where each detectors or sensors have unique identity. Therefore, each device has its own identity which makes it easier to identify which device has been triggered and spot the location of fire. The system quickly notifies the local responders to take the necessary action to stop further damage.
Overall, the conventional fire alarm is inexpensive and used in small building. however, the addressable fire alarm is very smart and sophisticated system which is very expensive but it is more reliable. Bottom line, conventional fire alarm should be installed in building where it is easier to spot the fire (such as in building having fewer rooms) While the addressable fire alarm should be installed in large buildings.
